To all whom. t may concern:

Be it known that I, WILLIAM D. SKID- Monn, a citizen of the UnitedStates, and a resident of the borough' of the Bronx, city and State ofNew York, have invented certain new and useful Improvements inDumping-Cars, of which the following is a speciication.

My invention relates to railroad cars, and more particularly to thatclass of cars known as dumping cars, such asl are used, for 1nstance, inrailway construction, for conveying ballast, filling material and thelike to such places where it may be needed, and dumping the same upon orbeside the right of way; and which may be used for other similarpurposes. The invention is also applicable to vehicles of other kinds.

The object of my invention is toprovide such a car which shall be simple1n conl struction and eii'cient in operation, and which is adapted todump its load on either side or both sides of the right of way, eithertherefrom, as may be desired, or between the rails, either closertheretoor in the middle of the track, and which, on account of its low centerof gravity, is capable of being constructed with a large carryingcapacity.

The invention consists in the novel construction, arrangement andcombination of various devices, elements and parts, as shown in theaccompanying drawings and fully described in this specification.

In the said drawings, Figure 1 is a side elevation of the car; Fig. 2;`is an enlarged elevation of one end with the trucks removed; Fig. 3 is adiagrammatic view showing my car arranged to dump on both sides of theright of wa at a distance from the rails; Fig; 4 is a iagrammatic Viewshowing an arran ement whereby the load is dumped at a distance outsidethe right hand rail only; Fig. 5 isi a diagrammatic view showing at theleft an arrangement whereby the load is dumped outside the rail andclose thereto, and at the right an arrangement by 22 is moved intotlost.

after described; Fig 9 is a view on an enlarged scale of the right handend of Fig. l; and Fig. 10 is a view on yan enlarged scale of the lefthand end of Fig. 1.

In carrying my invention into eifect in the embodiment thereof which Ihave selected for illustration in the accompanying drawings and'description in this specification, I provide for the lower portion ofthe car a running gearof the common or any suitable type, comprising thenecessary sills, holsters or the like, mounted upon bogie-trucksprovided with journal boxes forming the bearings for the ends of theaxles, and supported by and secured tothe running gear in any vsuitablemanner are end members 12 connected by means of a portion 13 adapted to'form part of the floor of the carrying body of the car.

Extending the length of the car are doors 14, hinged to the members 13at 15; door 16, hinged at 17; doors 18, hinged at 19; and doors 20,hinged at 21. The doors 14, 16 and 18, together with the portions 13,form the bottom of the carrying body, while the doors ,20 form thesides.

At one end and on each side of the car I provide levers 22 (see Figs. 7and 9). These levers 22 are pivoted on the outside of the members 12,,land each lever lis rigidly secured to a rod 23 running the length ofthe car. Rigidly mounted on the rods 23 are one or more supports 24,adapted when the lever 22 is in the position shown by the full lines inFig. 7 to support members 25 rigidly secured to the doors 14, and thushold the said door in its closed osition. When the lever Ihe positionshown bythe dotted lines 1n Fig. 7 the supports 24 are moved out' fromunder the members 25 in order that the door 14 may o en. The lever 22may be secured in itsfull ine position by means of a pin 26 passingtherethrough, which pin may be secured to the member 12 by. a chain 27,in. order that it may not be When the lever 22 is in its dotted lineposition, it rests against a block 28. After the door 14 has beenopened, it may be replaced in its closed posltion b means of a lever 29,which may be detac abl secured to a squared end 30, which is a roongaton of the hinge 15. Pawls 32 an ratchets 31 may be provided on theoutside of the member 12, at the ends of the said hinges 15.

' may be secured by pins 126 which may be The doors 16 aresupported inal similar manner by means of longitudinal rods 123, supports V124leXtendin upwardly therefrom adapted to engage wit members 125 on thedoor, and levers 122 rigidly mounted on one end of each of 'these rods,these levers 122 attached to chains 127 in order that they may notbelost. Each door 16 is provided which pawl is normally held in positionby' with a ratchet 37 engaged by a pawl 38,

a spring 40, but may be disengaged from the ratchet 37 by operating thehandle 39. The door 16 may be replaced in its closed position byapplying the lever 29 to the squared end 36, as will be readily under-lstood.

' near the to Secured to one end of each'hinge 21 is a toothed quadrant41. (See Figs. 1, 2 and 10). Each quadrant is secured by means ofa'removable-pin 45 to one of the doors 20, in order that it. may eitherbe ri id therewith, or swing on 21 as a pivot in e pendently of the saiddoor. A rod 42 is pivoted at 43 to each quadrant, and has its other endpivoted at 44 to one of the doors 18.

l provide levers 46, pivoted at 47, and provided with projections 48adapted to engzage with notches 68 on the quadrants 41.

ach of these projections normally engages y a notchin a quadrant, andholds the quadrant in whichever positionit may occupy,

being acted upon by the spring 49, but the projection may be disengagedby depressing a pedal 50, pivoted at 51. and adapted to` elevatealvertical rod 52.l The upper end of this rod 52 bears against the endof the lever 46 opposite to that which bears theprojection 48, raisesthis end, and so depresses the projection 48.

One pedal 50 is provided on each side of each end of the car, and thepedals on opposite ends of the same sides of the car are operativelyconnected together so thatl when one such pedal is depressed, thecorresponding pedal at the other end of the 'car will also be depressed.To accomplishthis i provide for each pedal a link 100 having one of itsends pivoted to the inner end of the said pedal. The other ends of thelinks 100 areA pivoted to rocking bars 101,

which bars extend inward to the transyerse i v center line of the car,being pivoted midway their length, at 108. To the inner end of each bar101 is pivoted one end of a link 102. Thus the quadrants 41 may bereleased from either end of the car also provide securin means 58,pivoted of the ens of the car, Aat 54, and normal y held in the positionshown by the full lines in Fig. 2'by means oit chains 55.. Each member53 is provided with a pin` 56,'

which, when the member occupies its yer tical position, as shown by thedotted lines at the right of Fig. 2, engages wlth one of suitab emanner, as by the quadrants 41, and will the'saidl vquadrant to swingdownward for a short distanceonly, when the projection 48is re-'Y i Iprovide a cylinder 5.7 having suitable stop-cocks 5,8, for compressedair or the like, and having a piston59 provided vwith a rod 60. This rod60 bears two vertical racks 61,

adapted to engage with toothed wheels 62,

mounted on shafts 63, which vshaftsals'o bear gear wheels 64 adapted toengage with the quadrants 41. rFhe shafts 63 are adapted to slidelongitudinally, as shownin Fig. 1, and when in its full line position toplace the gears 62 'and 64 in engagement with the racks 61 andquadrants-41 respectively, but

when in its dotted line position to disengagev said gears. Projectingfrom the members 12 are studs 65, over which may be slipped a gear wheel66 (see Fig. 8) adapted to rotate thereon, said gear wheel beingprovided with a handle 67 lwhereby it and a quadrant are disengaged, andthe pedal 50 depressed,

releasing the quadrants' 41, nd the doors 18 and 20. Under the weight ofthe load,

the weight of the quadrants 41, and the momentum acquired from theinitial push of the load, these 'doors open to their full extent, andare held so by the engagement of the projections 48 with theinnernotches 68 of the quadrants 41. The momentum of the falling load willthrow it away from direct contact with the rails.

When it is desired to close the doors, the

vpedal 50 is againdepressed, and the doors ,caused to move back intoposition byy hand or b the com ressed air. n

Wben it is esired to dump lfrom one side only, as shown in Fig. 4, the`pin 45 is withdrawn from each quadrant` of the door 20 which is not tobe used, thisdopr 20 being then swung inward into the position shown inFi 4, where it may be secured in any plassing pins through its loweriiange intojt e portion 13. The

` load may `then be placed on the car, and

wiii occu y the arca shown in cross-section by the s ading of Fig. 4. Todump, the mechanism on one side onl is employed..

When it isgdesired to' ump outside the track, 4but close to the rails,as shown at the left of Fig. 5, the members 53 are placed in engagementwith the quadrants 41, thus per- 4mitting the doors 18 and 20 to openJtor a short-distance only. The load drops out gradually and withoutmuch momentum,

and falls close to the rails.

When it is desired to dump in the center of the track, as shown at theright of Fig. 5, the doors 20 are swung inward, and angles or girders 69suitably secured to their lower edges, as b bolting the flanges of thesegirders and)-7 the doors 20 together. The lengthened door is thenlallowed to swing outward until'it rests against, the upper edge of thedoor 16. The load is. dumped through the doors 14, which are opened byydisengaging the pawl 32 from the ratchet 31, and operating the lever 22.After the load is dumped, the door may be closed by rotating the handle29, and the lever 22 then moved back to its full line position, thesupports 24 being sprung under the members 25.

When it is desired to dump between the rails, but close to them, asshown in Fig. 6,

the load is dumped through the doors 16,

which are opened by releasing the pawl 38 and disengaging thesupports bymeans of the levers 122 on the side of the car. The

operation of these doors is similar to the operation of the doors 14.The doors may be again closed by placing the handle 29 on the squaredends 36, the operation being similar to that of closing the doors 14,except that the handle is moved in the opposite direction.

The advantages of my invention `will be obvious from what has been abovesaid concerning its construction and mode of operation, and consistsnotably of fthe various manners in which the car may be caused to dumpits load and its low center of grav'- ity, which beingFlocatedapproximately at the point of ig. 3, will permit a large load to belcarried. I do not limit myself to the exact form described, as it isobvious that various modifications might be made, without departing fromthe spirit and scope of my invention.
